C 173-94

Meter made from PVC and FRP. Very similar in design to model C-440. It weighs only 5.5 lb (2.5 kg). It features non threaded construction for easy use. A stainless steel “V” clamp holds the two C-445 halves together. “O” ring seals prevent leakage. Expansion plug top. This Meter meets ASTM C 173-94 except for not being "constructed out of machined metal”. The base volume is 134 in3 (2.2 dm3) and the sight tube reads from 0-9%. Supplied as a kit, it includes the meter, syringe, tamping rod, strike off bar, funnel, mallet, calibrated cup and a hard sided plastic carrying case. C-445

Pressure Type “B” Meter

A Volumetric Air Meter measures air entrainment in fresh concrete by the “Volumetric Method.” Air is removed from a known volume of concrete by agitation in an excess of water. It may be used with any type of aggregate including light weight and porous material. The test is not affected by atmospheric pressure and the specific gravity of the material need not be known. A direct reading sight gauge is built-in to the instrument. The base has a volume of 130 in3 (2.13 dm3) and the sight tube reads 0-10%. These Meters can be used as a pycnometer to determine the specific gravity of cement, sand or gravel as well as the percent of free-water in damp sand and gravel.

C-440A

C-440 is machined bronze. The base and upper chamber of model C-440A is constructed of machined aluminum. Either model is supplied in a transport case with straight edge, measuring cup, tamping rod, syringe, baffle-bottom funnel and instructions. Volumetric Air Meter C-440

ASTM* C 231 AASHTO* T 152 * See Standards Buyer's Guide at www.DGSI.info/3000.

The Type “B” Meter measures the air content of fresh concrete based on the pressure-to-volume relationship of Boyles Law. Pressure is applied to the sample to compress the entrained air in the pores. The Type “B” Meter uses the change in known volume of C-435A air to determine the air content of the mix. The readings are not affected by changes in barometric pressure. This method is faster to use than the volumetric method. These meters are made from a corrosion resistant aluminum alloy with a heavy duty pump and built-in gauge (0-20%). The base has a volume of 1/4 ft3 (7 dm3) and can also be used for unit weight measurements. Instructions for use includes a chart for using the meter to determine the specific gravity of aggregates. Both kits include the meter, syringe, tamping rod, calibration vessel, strike-off bar and plastic carrying case. C-435

C 173, AASHTO T 196

These Calibration Vessels may be used with any 1/4 ft3 (7 dm3) Concrete Air Entrainment Pressure Meter. Their volume is precisely 354 ml which is exactly 5% air by C-44201P volume when placed in any 1/4 ft3 pressure meter bucket. Use two to check at 10%. It is best used if placed in a meter bucket pre-filled with water.

Air Indicator Kit AASHTO T 199 The test takes about 3 minutes to perform and is ideal for field use at either a pour site or batch plant. It may also be used to determine whether more thorough testing may be needed. The open end C-450 of the vial has a reinforced lip and extra graduation marks are included on the stem. The kit includes a 6¼ x 1⅛-in (159 x 28 mm) air indicator vial with stopper/cup, squeeze bottle for alcohol, brush and instructions in a plastic case. C-450
